  • Abstract Cooperative communication networks have attracted extensive attention recently, because it increases the reliability of communication systems and archives a better error rate performance. This thesis mainly considers a cooperative communication system in the presence of eavesdroppers. Based on the local summary statistics transmitted by relay nodes, the fusion center makes a global decision in favor of one of symbols sent from the source. However, the eavesdropper can also eavesdrop the information which is sent from a node to the fusion center and quantizes those raw observations to infer the information.
     This thesis adopts a distributed reception technique using coding theory for cooperative communication systems in the presence of eavesdroppers. Specifically, an “Exhaustive Search” method is utilized to search the best codebook in accordance with the criterion of the minimization of the error probability ratio of the fusion center and eavesdropper. The results obtained by our simulation show that the best codebook obtained according our proposed criterion does achieve a better system performance. In addition, the best structure of the codebook used for the system in the presence of eavesdroppers can be observed from the conducted simulation results.
